Hi, by my reading of 'man s_client', you have turned **off** ssl v3

        -ssl2, -ssl3, -tls1, -no_ssl2, -no_ssl3, -no_tls1, -no_tls1_1,  
-no_tls1_2
            these options disable the use of certain SSL or TLS 
protocols. By
            default the initial handshake uses a method which should be
            compatible with all servers and permit them to use SSL v3, 
SSL v2
            or TLS as appropriate.
